DESCRIPTION

HCF4020B is a monolithic integrated circuit

fabricated in Metal Oxide Semiconductor

technology available in DIP and SOP packages.

HCF4020B is a ripple carry binary counter. All

counter stages are master-slave flip-flops. The

state of a counter advances one count on the

negative transition of each input pulse; a high level

on the RESET line resets the counter to its all

zeros stage. Schmitt trigger action on the input

pulse line permits unlimited clock rise and fall

times.

All inputs and outputs are buffered.
